FPGA-based verification methodology of SoC-type CMOS image signal processor

This paper describes a FPGA-based verification methodology for the image signal processor (ISP) of system-on-chip (SoC) type CMOS image sensor. To make a verification environment, the complete ASIC prototyping system, the ARM7 TDMI CoreTile board and external interface boards — the sensor board, the USB board and the switch board — are used. As a verification method, 4-step verification strategy comprised of ARM-core based platform verification, system verification, algorithm verification and performance verification is used. Through this method, the 2M-pixel/3M-pixel ARM-based ISP of CMOS image sensor is verified very effectively before tape-out.
